The Values of the Caley Valley Wetlands
“The density of birds was astonishing, the highest I have ever seen in any wetland. It
was immediately clear that this was an extraordinary haven for wildlife”
Professor Callum Roberts (2013)

Executive Summary
Background
The Caley (Kaili) Valley Wetlands (the Wetlands) is a large, intact coastal wetland system located on the
central Queensland coast approximately 25 kilometres (km) northwest of Bowen. The Wetlands cover an
area of approximately 5,154 hectares (ha) and represents one of the few remaining intact wetland systems
between Townsville and Bowen supporting valuable habitat and a wildlife corridor for a range of threatened
flora and fauna species.
The Wetlands are a modified natural system that comprises of four out of the five main wetland systems
within the Great Barrier Reef catchment, including - Estuarine, Lacustrine, Palustrine, and Riverine. There are
at least six threatened native flora species within the Wetlands, remnant vegetation to the south that
provides valuable habitat and a wildlife corridor of state significance, which connects the Wetlands to
National Parks to the east and west.
The Wetlands support significant populations of waterbirds with over 40,000 birds and 154 bird species
recorded. The wetlands provide habitat for at least 22 species of migratory shorebirds and greater than 0.1
per cent of the flyway populations of the Red-necked Stint and Sharp-tailed Sandpiper and habitat for
threatened migratory species such as the Australian Painted Snipe, Little Tern, Australian Cotton Pygmy-
goose and the Eastern Curlew. The Wetlands also provides breeding habitat for at least 24 species and is the
largest and most northerly coastal nesting area for the Black Swan.
The habitats of the Wetlands also provide a diverse range of resources for a number of threatened fauna
species, including:
At least 10 species of waterbirds and shorebirds, including four migratory and six non-migratory
species.
Saltwater Crocodile, a non-avian wetland-dependent species.
Several marine turtle species, including the Green Turtle, Loggerhead Turtle and Flatback Turtle,
which feed and nest near the Wetlands.
Dugong and Snubfin Dolphins are also known to or likely to inhabit adjacent waters.
Other terrestrial species that potentially utilise the Wetlands or adjacent areas, including the
Squatter Pigeon, Black-throated Finch, Northern Quoll, Coastal Sheathtail Bat, Water Mouse, Single-
striped Delma, and Koalas.

Ownership
Abbot Point comprises of land designated as Strategic Port Land (SPL), owned by the North Queensland Bulk
Ports Corporation which includes the Port of Abbot Point, and the Abbot Point State Development Area
(APSDA). The Wetlands falls almost entirely within the APSDA and adjoins the Abbot Point international port
facility. Almost all the properties that comprise the Wetlands are owned by the Coordinator General.
Ramsar values
The Wetlands is recognised as a nationally important wetland, under the Directory of Important Wetlands
Australia (DIWA), and also meets the criteria for being recognised as a Ramsar wetland of international
importance.
Through assessing previous studies on the Caley Valley Wetlands and the Abbot Point area, the Wetlands is
likely to meet at least seven out of the nine Ramsar criteria, easily satisfying its potential for nomination. The
Wetlands:
Shows an outstanding example of wetlands on a tropical prograding coast.
Supports endangered species
o 24 endangered Australian Painted Snipe representing 2.3 per cent of the total population.
Supports populations of animal species important for maintaining biological diversity
o Provides one of Queensland’s largest and most northerly coastal nesting areas for Black
Swans.
Supports animal species at a critical stage of the life cycle
o Family groups of the endangered Australian Painted Snipe.
Regularly supports 20,000 or more waterbirds
o 41,088 recorded in dry season (June 2012), 21,077 in wet season (March 2012).
Regularly supports 1 per cent of a population of one species of waterbird
o Approximately 350 Little Tern species out of the estimated population of 3,000.
o 2.3 per cent of the Australian Painted Snipe population.
o Greater than 1 per cent of the total population of Purple Swamphens.
Important source of food for fishes, spawning ground, nursery and/or migration path
o Barramundi, Oxeye Herring and Longfin Eel, utilise both fresh and saltwater habitats to
complete their life cycles, and are found in the Wetlands area.
Current and Future Development
The Port of Abbot Point was built in the north east corner of the Wetlands in the 1980s. There is currently
one terminal (T1) which is under a 99 year lease to Mundra Port Pty Ltd, a subsidiary of Adani, and operated
by Abbot Point Bulk Coal Pty Ltd, a subsidiary of Xstrata. T1 has an export capacity of 50 Megatonnes of coal
per annum (Mtpa). In 2013/2014 T1 exported 22.89 Mtpa of coal (45 per cent of its capacity).
The scale of proposed port expansions at Abbot Point Coal Terminal is enormous. Two major terminal
expansions have been approved for the area, referred to as Terminal 0 and Terminal 3. A third terminal (T2)
proposed for the area has been withdrawn by BHP. Two additional developments, Abbot Point Expansion
Project (AP-X) and Waratah Coal terminal, have also been proposed for south of the Caley Valley Wetlands.
Combined these port expansion projects will create one of the world’s largest ports across the Caley Valley
Wetlands and on the doorstep of the Great Barrier Reef.
Page 4 of 51
The proposed port expansion poses the greatest threat to the Wetlands and are likely to further remove
parts of the Wetland habitats, increase noise and pollution in the area, and threaten the survival of many
important species, such as the endangered Painted Snipe.

Biological significance Shallow waters and wetlands provide up to 40 per cent of global renewable ecosystem services, and
remarkably they only cover 1.5 per cent of the earth’s surface (WetlandCare Australia 2008).
Not only do wetlands buffer the impact of pollutants entering rivers, streams and the Great Barrier Reef,
they also support a high level of biodiversity, provide flood control, groundwater discharge and water
purification (WetlandCare Australia 2008). The most significant impacts on coastal systems from coastal
development, in the Great Barrier Reef catchment, have been the loss of coastal wetlands with an estimated
70 to 90 per cent already lost (GBRMPA 2009).
The Caley (Kaili) Valley Wetlands (the Wetlands) is a large, intact coastal wetland system located on the
central Queensland coast approximately 25 kilometres (km) northwest of Bowen. The Wetlands cover an
area of approximately 5,154 hectares (ha) and are listed under the Directory of Important Wetlands in
Australia (DIWA). The Wetlands are a slightly modified natural system that represent one of the few
remaining intact wetland systems between Townsville and Bowen and support a wide range of habitats for
critical bird species.
Environmental Values
The Caley Valley Wetlands is recognised as a nationally important wetland, under the Directory of Important
Wetlands Australia (DIWA) on the basis of the following criteria:
1. It is a good example of a wetland type occurring within a biogeographic region in Australia;
2. It is a wetland that plays an important ecological or hydrological role in the natural functioning of a
major wetland system/complex;
3. It is a wetland that is important as the habitat for animal taxa at a vulnerable stage in their life
cycles, or provides a refuge when adverse conditions such as drought prevail;
4. The wetland supports one per cent or more of the national populations of any native plant or animal
taxa; and
5. The wetland supports native plant or animal taxa or communities which are considered endangered
or vulnerable at the national level.
The site provides an outstanding example of wetlands on a tropical prograding coast (SEWPAC 2010a).
Permanent water, a wide range of wetland habitats, very rich food resources and sheltered roosting and
breeding sites cause the site to be exceptionally important for waterbirds. The importance of the site is such
that it meets criteria for identifying wetlands of international importance adopted by the Ramsar Convention
(e.g. 1a, 1c, 2a, 2c) (SEWPAC 2010a), however is yet to be recognised.
Wetland types
The Wetlands is located on a low-lying prograded coastal plain west of the Don River delta (SEWPAC 2010a).
It comprises a complex continuous wetland aggregation of intertidal mudflats, sand flats, estuary channels,
mangroves and saltmarshes under tidal influence in its western extent, and predominantly non-tidal,
freshwater marshes within an artificial bund in its eastern extent (BAAM 2012a; SEWPAC 2010a).
It occurs within an area substantially altered by clearing and ongoing pressures from agricultural activities,
such as grazing. Although the vegetation is modified it represents a key fauna movement corridor of state
significance (BMT WBM 2010).
Page 8 of 51
The Wetlands comprise of four out of the five main wetland systems within the Great Barrier Reef
catchment (refer to Figure 1), including: Estuarine (brackish waters at the marine-freshwater interface),
Lacustrine (lakes and dams), Palustrine (marsh or swamp) and Riverine (rivers or deepwater habitats in a
channel). A very small percentage of the Wetlands is artificial and modified. Refer to Table 1 below.
Table 1. Wetland System Statistics
System Area (km2) % wetlands area % total area
Total 36.5 100.0% 70.9%
Artificial and highly
modified 0.1 0.3% 0.2%
Estuarine 24.3 66.5% 47.2%
Lacustrine 0.1 0.3% 0.2%
Palustrine 11.9 32.6% 23.1%
Riverine 0.1 0.3% 0.2%
Based on 2009 wetland mapping. There are approximately 8 lacustrine/palustrine wetlands in this region. Areas do not include marine or estuarine waters but do include estuarine wetland vegetation (e.g. mangroves and tidal flats). (source: WetlandInfo 2013a)
BMT WBM (2012) identified six broad functional zones in their baseline report based on landform types,
salinity characteristics and vegetation communities (refer to Figure 2):
1. Coastal Zone - located on the western side of the Wetlands and is comprised of marine habitat
types.
2. Western Estuarine Zone - located down-slope of the western (outer) bund and comprised of
estuarine vegetation, tidal flats and creeks.
3. Hypersaline Zone - located between the western (outer) and causeway (inner) bund, and contains a
mosaic of natural saltpan and degraded wetland habitat.
4. Wetland Basin Zone - forms the majority of the Wetlands and is comprised of a shallow lagoon with
fringing saltmarsh vegetation.
5. Saltwater Creek Zone - contains permanent freshwaters and riparian vegetation (including
mangroves).
6. Terrestrial Zone - contains small ephemeral streams as well as terrestrial ecosystems (i.e. woodlands
and grasslands.

Hydrodynamic Processes
The region has a tropical monsoon climate with distinct wet and dry seasons. The average annual rainfall
at Bowen is 1096 mm. December to March tend to be the warmest and wettest, while the driest months
occur in August and September.
Freshwater to the Wetlands is provided by runoff from the Salisbury Plain and the slopes to the south and
south east from Mount Roundback and Mount Little (BMT WBM 2012). During the wet season there is a
reversible movement of freshwater and brackish waters westwards from the Wetlands and into Curlewis
Bay (BMT WBM 2010). GHD surveys (2009) reported that in the wet season the Wetlands can be 18 km
long and 6 km wide, and cover an area of approximately 5,000 ha.
During the dry season tidal movements dominate the system with much of the Wetlands drying out with
very limited inflow (BMT WBM 2010). One of the few permanent non-tidal waterbodies in the Wetlands is
known as Lake Caley (or Kaili) and during extended dry periods groundwater may be the predominant
source of water (BMT WBM 2010).
Tidal exchange occurs via Mount Stuart and Branch Creeks in the western sections, and possibly Saltwater
Creek in the eastern section of the Wetlands (BMT WBM 2010). Three artificial bunds influence the
hydrology of the Wetlands, including the western (outer) bund, causeway (inner) bund, and eastern bund
near the rail crossing on Abbot Point Road (BAAM 2012a). Tidal flushing is somewhat constrained by the
western and causeway bunds (refer to Figure 2). The western (outer) bund was constructed to improve
habitat for waterfowl by duck shooters in the area, and the causeway (inner) bund incorporates a water
delivery pipeline to the Port of Abbot Point and vehicle access (BMT WBM 2010).
Water Quality
Surface water quality is largely driven by the fluvial hydrology, groundwater and tidal influences, with
other influences from treated water runoff from the Port of Abbot Point located to the north of the
Wetlands, and runoff from the elevated dunes and ridges within the Abbot Point Coal Terminal which
enter the Wetlands from the east (BMT WBM 2012; GHD 2009). BMT WBM (2012) reported a salinity
gradient within the Wetlands, resulting in the creation of marine, hypersaline brackish and freshwater
waterbodies.
Groundwater Quality
Studies by PB (2009) note the following groundwater conditions in the Wetlands:
- Likely to be shallow groundwater levels;
- High correlation between surface elevation and groundwater levels, with groundwater levels
predicted to range between 0-2 m below groundsurface;
- Close proximity to coast means groundwater likely to be at freshwater/saltwater interface; and
- Combination of a density difference at freshwater/saltwater interface and shallow gradients are
the dominant hydraulic features controlling groundwater movement and water levels.
Licensed bores are located within the vicinity of the Wetlands with the groundwater water quality
guidelines being exceeded at bores on land adjacent to the northeast corner of the Wetlands (where the
Port of Abbot Point is located) (BMT WBM 2012). Analytes that exceeded relevant water quality
guidelines were total arsenic, aluminium, cadmium, chromium, copper, lead, manganese, nickel and zinc.
GHD (2009) also considered iron and sulphate concentrations elevated and may be associated with
Page 12 of 51
infiltration of runoff contaminated from coal stockpiles, leakage of APCT settlement ponds into
groundwater and/or a natural occurrence related with acid sulphate soils or marine sediments.
Flora
South of the Wetlands hosts a mosaic of remnant forest and cleared grazing lands, with most of the
lowland areas cleared of native vegetation in favour of introduced grass species for cattle grazing (BMT
WBM 2012). Remnant vegetation covers steeper areas (e.g. Mount Roundback), and patches of scattered
trees occur along the banks of the numerous small creeks that drain into the Wetlands (BMT WBM 2012).
Between Mount Curlewis and Mount Little the fringing coastal vegetation is largely intact with the
exception being around Abbot Point Coal Terminal (APCT) (BMT WBM 2012).
This remnant vegetation provides a valuable habitat and wildlife corridor for a range of flora and fauna
species. A large portion of the Wetlands and the remnant vegetation along Branch Creek south of the
Wetlands is mapped as State Significant Corridor Vegetation, connecting Wetland to Mount Aberdeen
National Park 40km southwest of Bowen. The largely intact coastal vegetation also provides relatively
good habitat connectivity between the Wetlands and Cape Upstart National Park. However, there is poor
connectivity in a direct line (north to south) between the Wetlands and the ranges due to extensive
clearing for grazing (BMT WBM 2012) (Refer to Figure 3).
The clearing of lands and growth of weeds, which in some parts are the dominant vegetation, represent
key pressures to native vegetation.
Six threatened flora species have been identified as known to or likely to occur within the Wetlands (PB
2009 and BAAM 2012a). These include:
- Aristida granitica – perennial grass with potential to occur given Abbot Point is within the species
range and there is possible suitable habitat within the Wetlands (PB 2009). Listed as Endangered
under the NC Act and EPBC Act, and not yet assessed by the IUCN.
- Eucalyptus raveretiana – recorded on the banks of Salt Water Creek by Chris Hansen of Hansen
Botanical Assessments Pty Ltd in December 2008 (PB 2009). Listed as Vulnerable under the NC Act
and EPBC Act, and not yet assessed by the IUCN.
- Croton magneticus Airy Shaw – small tree or shrub known to occur with one existing record
located at Abbot Point (DERM 2010 and BAAM 2012a). Listed as Vulnerable under the NC Act and
EPBC Act, and not yet assessed by the IUCN.
- Leucopogon cuspidatus – dwarf to small shrub with potential to occur given Abbot Point is within
the species range and there is possible suitable habitat within the Wetlands (BAAM 2012a). Listed
as Least Concern under the NC Act and Vulnerable under the EPBC Act, and not yet assessed by
the IUCN.
- Ozothamnus eriocephalus – woody shrub with potential to occur given Abbot Point is within the
species range and there is possible suitable habitat within the Wetlands (BAAM 2012a). Listed as
Vulnerable under the NC Act and EPBC Act, and not yet assessed by the IUCN.
- Taeniophyllum muelleri – minute epiphytic orchard with potential to occur given Abbot Point is
within the species broad distribution and there is possible suitable habitat within the Wetlands
(BAAM 2012a). Listed as Least Concern under the NC Act and Vulnerable under the EPBC Act, and
not yet assessed by the IUCN.

Estuarine Habitats
Since the construction of the western (outer) bund in the 1950’s, approximately 46 ha of mangrove forest
have been lost from Estuarine Habitats and replaced with saltpan habitat, as a result of alterations to tidal
hydraulics associated with the western bund (BMT WBM 2012; GHD 2010). Mangroves occur mainly on
the western side of the site associated with three tidal channels flowing into Curlewis Bay (SEWPAC
2010a).
BMT WBM (2012) recorded the Milky Mangrove (Excoecaria agallocha) as the dominant mangrove
species in the portion of Saltwater Creek Zone within the Wetlands where there are low salinity waters.
By contrast, species such as Red Mangrove (Rhizophora stylosa) and Yellow Mangrove (Ceriops tagal)
which co-dominate in the Western Estuarine Zone, were generally confined to areas with salinities near
full marine conditions. Grey Mangrove (Avicennia marina), which has a wide salt tolerance, was recorded
in both the Western Estuarine Zone and Saltwater Creek Zone (SEWPAC 2010a; BMT WBM 2012).
Dominant estuarine habitat is the saltmarsh and saltpan areas occurring landward of mangrove forests
(BMT WBM 2012). Saltpans typically have very low cover of vascular plants (trees, shrubs, grasses),
although salt tolerant benthic algae can form a crust. SEWPAC (2010a) recorded halophytic scrub-shrub
species (saltmarsh) on the landward margins of these saltpans, including Halosarcia halocnemoides, H.
indica, H. pergranulata, Suaeda arbusculoides, Tecticornia australasica, Sarcocornia quinqueflora, and
Sporobolus virginicus (SEWPAC 2010a; BMT WBM 2012).
Palustrine and Lacustrine Habitats
Field observations in the BMT WBM (2012) October 2010 – November 2010 study suggest that Mangrove
Clubrush (Schoenoplectus littoralis) represented the dominant macrophyte species within standing waters
(SEWPAC 2010a; BMT WBM 2012).
Rivers and Streams
During BMT WBM (2012) surveys, Saltwater Creek was observed to have relatively homogenous
vegetation along much of its length which was dominated by a mix of Weeping Teatree (Melaleuca
leucadendra), Milky Mangrove (Excoecaria agallocha) and White-flowered Black Mangrove (Lumnitzera
racemosa). There are also scattered Forest Red Gum (Eucalyptus tereticornis).
Introduced species of tree, shrub and vine weeds occurred in the mid-storey, with Prickly Acacia (Acacia
nilotica) (Declared Class 2 Pest Plant - DAFF), Rubber Vine (Cryptostegia grandiflora) and Parkinsonia
(Parkinsonia aculeata) (Declared Class 2 Pest Plant - DAFF) representing the most abundant mid-storey
species (BMT WBM 2012).
Groundcover species included a variety of herbaceous weeds and grasses, with dense stands of the
samphire, Tecticornia australis and Marine Couch in low lying areas along the banks.
Thickets of reeds and sedges, particularly Mangrove Clubrush and Water Chestnut (Eleocharis
dulcis), dominated the littoral zone of Saltwater Creek. The submerged aquatic Water Thyme
(Hydrilla verticillata) formed dense masses, with the introduced Curly Pondweed (Potamogeton
crispus) sub-dominant. Giant Water Lily (Nymphaea gigantea) was widespread throughout Saltwater
Creek and Swamp Lily (Ottelia ovalifolia) was moderately abundant (BMT WBM 2012).
SEWPAC (2010a) also reported beds of emergent grasses such as spiny mudgrass (Pseudoraphis
spinescens) and Cynodon dactylon and smaller sedges such as Cyperus zollingeri and Cyperus scaber may
also be present, particularly on the landward edge of the site. Other species present include Nymphaea
Page 15 of 51
gigantea, Nymphoides indica, Persicaria subsessilis, Marsilea drummondi, Ottelia alismoides and
Pseudoraphis spinescens. All species are either not listed or listed as Least Concern by the NC Act.
Other flora adjacent to the Wetlands
Seagrass
Extensive seagrass meadows have been mapped within Abbot Point port limits and are the dominant
benthic habitat, as shown in Figure 4 (Abbot Point EMP 2010). These meadows are likely to play
important ecological roles including providing food for endangered and threatened species such as
dugong and turtles, and a nursery for commercial fish species.
A seagrass survey at the Port of Abbot Point of coastal and deepwater seagrass conducted between June
2010 and September 2011 indicated that seagrasses are in a vulnerable state (McKenna and Rasheed
2011). Significant losses of coastal seagrass density and distribution have been observed and the
cumulative impacts of natural stressors combined with the increased level of impact from port activities
and development are putting seagrass at a heightened risk of further loss (McKenna and Rasheed 2011).
Figure 4. Seagrass distribution at Abbot Point (source: Abbot Point EMP 2010).
Fauna
The habitats of the Wetlands provide a diverse range of resources for a number of fauna species. A range
of threatened species have been reported or are known to occur in and adjacent to the Wetlands. These
include:
Page 16 of 51
- At least 10 species of waterbirds and shorebirds, including four migratory and six non-migratory
species.
- Saltwater Crocodile, a non-avian wetland-dependent species.
- Several marine turtle species, including the Green Turtle, Loggerhead Turtle and Flatback Turtle
that feed and nest adjacent to the wetland.
- Dugong and Snubfin Dolphins are also known to or likely to inhabit adjacent waters.
- Other terrestrial species that potentially utilise the Wetlands or adjacent areas, including the
Squatter Pigeon, Black-throated Finch, Northern Quoll, Coastal Sheathtail Bat, Water Mouse,
Single-striped Delma, and Koalas.

Migratory and Resident Birds
The Wetland has high values for waterbirds and supports significant populations of both migratory and
resident shorebirds. Coastal and estuarine habitats, together with saltpans, represent feeding and
roosting areas and important breeding and dry season areas for a range of migratory and resident
shorebird species.
BMT WBM (2012) identified a number of factors that maintain the Wetlands habitat values for migratory
and non-migratory shorebirds. These include: habitat diversity and connectivity, habitat condition, tidal
processes, lack of human activities and hydrology.
The Wetlands support a significant population of waterbirds with greater than 20,000 recorded
(maximum survey count 41,088 in the dry season 2012 and 21,077 in the wet season 2012 (BAAM
2012b)), and boasts records of more than 154 species and breeding habitat for at least 24 species
(BirdLife Australia’s Atlas of Australian Birds 2012).
Migratory Shorebirds
Most migratory wetland species breed in northern China, Mongolia, Siberia and Alaska during June and
July and then migrate to Australia, a distance of up to 26,000 km for the non-breeding season (SEWPAC
2009; BMT WBM 2012). During their non-breeding phase they inhabit the southern hemisphere, arriving
in Australia in October and feeding mainly on intertidal invertebrates at low tide. In April, these birds fly
from their Australian feeding grounds to breed in the tundra areas of the northern hemisphere (SEWPAC
2009).
Under the EPBC Act a person must not take an action that has, will have, or likely to have a significant
impact on a listed migratory species. The Wetlands are known to provide important habitat for at least 22
species of migratory shorebirds (22 recorded during BMT WBM (2012) surveys and ~24 recorded in BAAM
(2012a) surveys). The Wetlands provides habitat to greater than 0.1 per cent of the flyway populations of
the Red-necked Stint and Sharp-tailed Sandpiper, an important population of Latham’s Snipe and the

threatened Australian Painted Snipe, Little Tern, Australian Cotton Pygmy-goose and Eastern Curlew (BMT
WBM 2012 and BAAM 2012a).
Australian Painted Snipe (Rostratula australis)
• BAAM (2012a) survey reported a total count of 24 Australian Painted Snipe with family
groups observed, suggesting breeding activity. The total represents 2.3 per cent of the
species’ total population in Australia, at between 1,000 and 1,500 mature individuals
(BirdLife Australia 2012). This makes the Wetlands an important site for the species in
Australia.
• Area of occupancy has decreased by over 50 per cent in three generations, with a
continued reduction in numbers exceeding 20 per cent over two generations (BirdLife
Australia 2012). BirdLife Australia (2012) stated that the “Caley Valley Wetlands, south of
Abbot Point, is typical of habitat preferred by APS and is considered by the Recovery
Program to be of very high international significance for the species”.
• Listed as Vulnerable under the NC Act, Endangered Migratory shorebird species under the
EPBC Act, and Endangered by the IUCN.
• Listed under the China-Australia Migratory Bird Agreement (CAMBA).

Little Tern (Sterna albifrons)
• Recorded in several studies carried out in the Wetlands and is the only migratory wader
species that has been recorded in internationally significant numbers within the
Wetlands.
• BMT WBM (2012) survey observed a high abundance of Little Tern (~350 individuals). The
current estimated breeding numbers in Australia is 3,000 mature individuals (SEWPAC
2011b) indicating that the population within the Wetlands meets internationally
significant numbers (≥1 per cent) under Ramsar criteria (BMT WBM 2012).
• BMT WBM (2012) stated that “the Wetlands may represent an internationally significant
location for this species” and “most of the Wetlands project area would provide suitable
feeding and breeding areas for this species”. It is expected that habitat usage will vary
over time, responding to changes in food and wetland hydrology (BMT WBM 2012).
• Listed as Endangered under the NC Act, Migratory Marine under the EPBC Act, and Least
Concern by the IUCN.
• Listed under the Japan-Australia Migratory Bird Agreement (JAMBA), CAMBA, Republic of
Korea-Australia Migratory Bird Agreement (ROKAMBA), and under the Convention on the

Resident Waterbirds and Shorebirds
In addition to the migratory species, numerous species of resident waterbirds and shorebirds have been
recorded within the Wetlands (BMT WBM 2012). The more estuarine/brackish and freshwater sections of
the Wetlands represent important waterfowl feeding, roosting and breeding areas. Waterfowl can be
extremely abundant east of the causeway (inner) bund in the wet season, with thousands of individuals
recorded.
At least six threatened resident waterbird species were recorded or are likely to occur in the Wetlands:
Black-necked Stork (Ephippiorhynchus asiaticus) (BMT WBM 2012)
• Adults and juveniles were recorded at a variety of locations within the Wetlands. BAAM
(2012b) recorded 12 individuals in March surveys.
• Near Threatened under the NC Act.
Beach Stone-curlew (Esacus magnirostris) (BMT WBM 2012)
• BAAM (2012b) February surveys observed 3 individuals in the Wetlands.

During BAAM (2012a) surveys a total number of 29 species of shorebirds were recorded at Abbot Point,
including the following:
Red-capped Plover (Charadrius ruficapillus)
In large numbers of 191 individuals recorded
by GHD (2010) in the wet season, 712
recorded by BAAM (2012b) in February 2012,
and BMT WBM (2012) also recorded high
numbers in Wetlands.
Australian Pratincole (Stiltia isabelle)
14 recorded by BAAM (2012b) June surveys.
Fish
No fish species currently recorded in the Wetlands are listed as threatened under EPBC Act or NC Act, and
none are considered threatened or near threatened under IUCN Red List.
The Wetlands support a broad range of fisheries habitats. Important fish habitats within the Wetlands
project area include the main drainage of Saltwater Creek and Lake Caley. The Western Estuarine Zone,
which is largely located outside the Wetlands project area, contains a range of habitats important to
fisheries species. Connectivity between the Western Estuarine Zone and Wetlands project area is
restricted by the two bunds (BMT WBM 2012).
Based on surveys by GHD (2010) and BMT WBM (2012) 25 fish species in the Wetlands have been
recorded, including estuarine and freshwater representatives. An additional four fish species are known
from the wider Don River basin and are expected to occur in the Wetlands.
One introduced species has been recorded within the study area, namely the Eastern Gambusia
(Gambusia holbrooki). The Eastern Gambusia is declared a pest species under the Fisheries Act 1994 and
Fisheries Regulation 1995 (BMT WBM 2012).
Many fish species found within the Wetlands, such as Barramundi (Lates calcarifer), Oxeye Herring
(Megalops cyprinoides) and Longfin Eel (Anguilla reinhardtii), utilise both fresh and saltwater habitats to
complete their life cycles. Many of these species are catadromous, spawning in marine environments and
spending the rest of their life-cycle in estuarine and freshwater environments. Species such as Moses
Perch (Lutjanus russelli) spends the majority of their adult life as a reef-associated species, whereas
juveniles utilise coastal wetlands as nurseries (BMT WBM 2012).
Mammals
In and around the Wetlands, over 23 species of mammals have been recorded (23 by BMT WBM (2010)
surveys and 26 by GHD (2009) surveys). Five of these are introduced species with the remainder listed as
Least Concern except for the Short-beaked Echidna (Tachyglossus aculeatus), which is listed as Special
Least Concern under the NC Act (BMT WBM 2010).

Amphibians
Eleven native frog species and the introduced Cane Toad (Rhinella marinus) have been recorded by BMT
WBM (2012) within the Wetlands. All of these species are currently listed as least concern under the NC
Act and are not listed under the EPBC Act. Based on BMT WBM (2012) research, the Wetlands do not
contain potential habitat for other threatened frog species known from the wider region. Most of these
species utilise terrestrial environments as adults, and breed in ephemeral ponds, creeks and non-saline
palustrine environments.
Reptiles
The most abundant reptiles were skinks and snakes (GHD 2009). Within and adjacent to the Wetlands
there have been more than 20 species of non-aquatic reptiles recorded (22 by BMT WBM (2010) and 26
by GHD (2009)), including the threatened Dunmall’s Snake (Furina dunmalli) which favours terrestrial
habitats (BMT WBM 2010). The species is listed as Vulnerable under the NC Act and EPBC Act, and
Vulnerable by IUCN.
Turtles
Two species of freshwater turtles have been recorded in the Wetlands (BMT WBM 2012 and GHD 2009).
These include the Snake-necked turtle (Chelodonia longicollis) and Cann’s Long-necked turtle (Chelodina
rankini formally Chelodonia cannii) are listed as least concern under the NC Act. A third species Elseya sp.
(possibly irwini) was observed (but not captured) in Saltwater Creek upstream of the Abbot Point Access
Road bridge in the BMT WBM October 2010 – November 2010 survey.
Green Turtles (Chelonia mydas) and Flatback Turtles (Natator depressus), both listed as vulnerable under
the EPBC Act and the NC Act, were noted as nesting along the beach between Abbot Point and Euri Creek
(Bell 2003). However, BMT WBM (2012) states these species have not been recorded in the Wetlands
project area to date, but may nest in Curlewis Bay within the boundary of the Wetlands (but outside the
APSDA).

Creek to the east of the Wetland and are believed to nest within the northwest boundary
of the Wetland. Credit AMCS
Page 25 of 51
Bell (2003) undertook a twelve month Marine Turtle study at Abbot Point (refer to Figure 5). He reported:
- A total of 49 Green Turtles and one Loggerhead Turtle were captured within foraging and
courtship areas.
- Green turtle population comprised of 27 per cent adults, 12 per cent pubescent and 61 per cent
pre-pubescent (juvenile).
- Halodule uninvervis was the only seagrass species found in the mouths of six foraging Green
Turtles.
- Small population of Green Turtles (<50 turtles) utilise sub-tidal rocky reef that parallels beach for
~2.5km south from Abbot Point, as foraging and resting habitat.
- Small population of Green Turtles reside inside and adjacent to the mouths of Saltwater and Euri
Creeks.
- A transect of the beach between Abbot Point and Euri Creek revealed:
9 nesting turtle tracks recorded (3 Green Turtle; 6 Flatback Turtle)
No evidence of feral animal predation on nests.
Four Green Turtles (3 juvenile and 1 adult) caught in Euri Creek, two adults and 1 juvenile
observed but not caught.
One dugong and one adult Green Turtle sighted ~150m offshore immediately adjacent to
Abbot Point coal loading facility.

Saltwater Crocodile
BMT WBM (2012) surveys did not detect any evidence of recent Saltwater Crocodile activity within the
Wetlands; however evidence has been recorded in the downstream section of Goodbye Creek on the
eastern side of the Wetlands (PB 2009). The Saltwater Crocodile (Crocodylus porosus) is listed as
migratory marine under the EPBC Act and vulnerable under the NC Act. BMT WBM (2012) states that the
Wetlands are not considered to represent high quality habitat for this species.

Other Terrestrial Fauna
Threatened species
Studies of the Wetland region have also noted the presence of the:
Single-striped Delma (Delma labialis)
Large legless lizard, listed as vulnerable under the EPBC Act and NC Act, and Vulnerable by
the IUCN.
Black-throated Finch (Poephila cincta)
• One pair observed near Splitter’s Creek during PB (2009) studies.
• Endangered under the NC Act and EPBC Act, and endemic to Australia.
Squatter Pigeon (Geophaps scripta scripta)
• Numerous records from previous surveys including BAAM (2012) surveys.
• Vulnerable under the NC Act and EPBC Act.
Several other threatened species were identified as occurring or likely to occur in or adjacent to and in the
Wetlands, including:
Northern Quoll (Dasyurus hallaucatus)
One of the five known isolated populations of northern quolls in Queensland is centred in
the Townsville/Bowen area. Survey work by Woinarski et al. (2008) suggests that the
Townsville/Bowen population is one of the three most important. Recent and impending
extinction of quoll populations in the Northern Territory and Western Australia makes this
population important for the conservation of the species, and is also significant as they
have survived the cane toads (Burnett 2008).
Wildlife Online database (2013) shows that 43 Northern Quoll have been reported within
the Whitsunday Regional Council boundary.
The Quoll Seekers Network has stated that recent sightings have been reported for the
areas surrounding the Caley Valley Wetlands, including Bogie (07/05/2013) and one South
in Bloomsbury (24/02/2013), one from Benholme (14/11/2012), Crystal Brook
(29/02/2013), and quite a few from further north in the Alligator Creek region close to
Townsville (Personal communications May 2013).
Least Concern under the NC Act, Endangered under EPBC Act, and Endangered by the
IUCN.
Coastal Sheathtail Bat (Taphozous australis)
Vulnerable under NC Act, not listed under the EPBC Act, and Near Threatened by the
IUCN.
Water Mouse (Xeromys myoides)
Vulnerable under the NC Act and EPBC Act, and Vulnerable by the IUCN.
Koala (Phascolarctos cinereus)
Widespread Koala habitat in the Brigalow Belt North bioregion, within which Abbot Point
is located. Thirteen confirmed records in the Whitsunday Regional Council Local
Government Area, with two within a 25 km radius of the Wetlands (Abbot Point CIA
2013).
Least Concern under the NC Act, Vulnerable under the EPBC Act, and Least Concern by
the IUCN.
Dugong (Dugong dugon)
Wildlife Online database (2013) states that 32 Dugong have been reported within the
Whitsunday Regional Council boundary.
Page 27 of 51
Extensive seagrass meadows surveyed in the area which play an important ecological role
providing food for dugong.
Vulnerable under the NC Act, Migratory Marine under the EPBC Act, and Vulnerable by
the IUCN.
Australian Snubfin Dolphin (Orcaella heinsohni)
Likely to occur offshore to Abbot Point due to suitable habitat. Wildlife Online database
(2013) states that 6 Australian Snubfin Dolphins have been reported within the
Whitsunday Regional Council boundary.
Near Threatened under the NC Act, Migratory under the EPBC Act, and Near Threatened
by the IUCN.
Introduced species
Within the Wetlands area feral pigs are the most abundant and destructive feral animal in the Wetlands.
Also present are wild dogs, Rabbits, Red Fox, Black Rat, House Mouse, Goat, Common Starling and Cane
Toad (GHD 2010; BMT WBM 2012). Feral cats, Common Myna and Asian House Geckoes are also likely to
inhabit the Wetland. Common Myna and Common Starlings are aggressive birds which compete with
native species for nest hollows and food (BMT WBM 2012).

RAMSAR – wetlands of international importance
Ramsar sites are listed under the Convention on Wetlands because of their international importance in
one or more areas, which may include ecology, botany, zoology, limnology or hydrology (Refer to
Appendix B for detailed criteria) (SEWPAC 2010b).
Current Ramsar sites in Queensland (WetlandInfo 2013):
- Moreton Bay
- Bowling Green Bay
- Currawinya Lakes
- Shoalwater Bay and Corio Bay
- Great Sandy Strait
The Caley Valley Wetlands are likely to meet several of the criteria for Ramsar listing as outlined in the
below table.
Table 2. Criteria for identifying Wetlands of International Importance.
Ramsar Criteria Equivalent DIWA criteria
Caley Valley Wetlands Criteria met
Group A of the Criteria. Sites containing representative, rare or unique wetland types
Criterion 1: A wetland should be considered internationally important if it contains a representative, rare, or unique example of a natural or near-natural wetland type found within the appropriate biogeographic region.
1, 2 Some areas are considered to be in near natural condition. None of wetland types are considered unique or rare in the drainage division. The site provides outstanding representative examples of intertidal marshes on a prograded tropical coast. However, it is uncertain whether this is significant at a bioregional scale. (BMT WBM 2012)
Possibly/Likely
Group B of the Criteria. Sites of international importance for conserving biological diversity
Criteria based on species and ecological communities
Criterion 2: A wetland should be considered internationally important if it supports vulnerable, endangered, or critically endangered species or threatened ecological communities.
5 Internationally important Australian Painted Snipe (internationally recognised endangered waterbird) found in the area. Total count of 24 recorded during BAAM 2012a June survey represents 2.3% of the species’ total population in Australia.
Confirmed. Wetland proven to support vulnerable and endangered species.
Criterion 3: A wetland should be considered internationally important if it supports populations of plant and/or animal species important for maintaining the biological diversity of a particular biogeographic region.
N/A Black Swan (Cygnus atratus) - one of Queensland’s largest and most northerly coastal nesting areas.
Likely. EPA (2006) considers that the site plays an important role in maintaining biological diversity in the region, by providing one of Queensland’s largest and most northerly coastal nesting areas
Page 29 of 51
for Black Swans (Cygnus atratus) and one of the most important post breeding concentration areas for waterfowl in eastern Queensland. (BMT WBM 2012)
Criterion 4: A wetland should be considered internationally important if it supports plant and/or animal species at a critical stage in their life cycles, or provides refuge during adverse conditions.
3 Australian Painted Snipe was recorded in ‘family groups’ during the BAAM 2012a June survey, where a total of 24 were counted.
Likely. The Lake is thought to provide an important refugia value during drought conditions. However, no studies have made a definitive assessment of the refugia values and functions at broad biogeographic scales. (BMT WBM 2012)
Specific criteria based on waterbirds Criterion 5: A wetland should be considered internationally important if it regularly supports 20,000 or more waterbirds.
N/A Total count of 41,088 wetland birds during dry season and total count of 21,077 in wet season (BAAM 2012b).
Likely. There are specific statistical measures for assessing whether a site ‘regularly’ supports a species. There are too few bird count data (in time and at whole of site scales) to assess this criterion. (BMT WBM 2012)
Criterion 6: A wetland should be considered internationally important if it regularly supports 1% of the individuals in a population of one species or subspecies of waterbird.
4 The current estimate for the number of breeding Little Terns in Australia is 3,000 (SEWPAC 2011b). The population of approximately 350 within the study area can therefore be considered a significant population. (BMT WBM 2012) Internationally important Australian Painted Snipe (internationally recognised endangered waterbird) found in the area. Total count of 24 recorded during BAAM 2012a June survey represents 2.3% of the species’ total population in Australia. ≥1 per cent of the total population for Purple Swamphen (Porphyrio porphyria melanotus) (Australia).
Possible. As for criterion 5. While Little Tern was observed to meet the 1% criterion in the BMT WBM October 2010 – November 2010 surveys, there is a need to assess whether such abundances are supported on a regular basis. However, in order to meet this criterion, internationally significant numbers would need to be recorded three out of any five year period. There is insufficient data to confirm whether this criterion is met by the Wetlands. Few broad scale bird surveys have been undertaken across the entire study area thus far, hence there is inadequate data to determine quantitative patterns in natural variability in waterbird abundance at this scale (BMT WBM 2012).
Specific criteria based on fish Criterion 7: A wetland should be considered internationally important if it supports a significant proportion of indigenous fish subspecies, species or families, life-history stages, species interactions and/or populations that are representative of wetland benefits and/or values and thereby contributes to global biological diversity.
4 (fish only) No. The Wetlands does not support a high level of fish diversity. (BMT WBM 2010)
Page 30 of 51
Criterion 8: A wetland should be considered internationally important if it is an important source of food for fishes, spawning ground, nursery and/or migration path on which fish stocks, either within the wetland or elsewhere, depend.
N/A Barramundi (Lates calcarifer), Oxeye Herring (Megalops cyprinoides) and Longfin Eel (Anguilla reinhardtii), utilise both fresh and saltwater habitats to complete their life cycles, and are found in the Wetland area.
Possible. Wetland values are constrained by presence of bund and water quality degradation. Estuarine creeks likely to support nursery habitat for species of fisheries significance, although lack of connectivity to freshwater areas limits values (at a bioregional scale) (BMT WBM 2012).
Specific criteria based on other taxa Criterion 9: A wetland should be considered internationally important if it regularly supports 1% of the individuals in a population of one species or subspecies of wetland-dependent non-avian animal species.
N/A Northern Quoll species sightings have been recorded around the Wetlands suggesting it is likely used as a habitat corridor for the Townsville/Bowen population.
Unsure. At present no species within the Wetlands are known or likely to be endemic to the region, nor have abundances exceeded the 1 per cent population criterion for non-avian species.
Site Location and History The Caley (Kaili) Valley Wetlands is a large coastal wetland system located on the central Queensland
coast approximately 25 kilometres (km) northwest of Bowen. The Wetlands cover an area of
approximately 5,154 hectares (ha) and located within the Don River Basin, which forms part of the
The Caley Valley Wetlands looking east. Credit Abbot Point Action Group.
Page 31 of 51
Brigalow Belt Region. The Wetlands fall within the Whitsunday Regional Council, the Bowen Shire and the
NQ Dry Tropics NRM Group (refer to Appendix C for further details).
Site Ownership
The ownership of Abbot Point comprises of land designated as Strategic Port Land (SPL) and the Abbot
Point State Development Area (APSDA) shown in Figure 6. The land to the North and East of the APSDA is
SPL, which is owned by the North Queensland Bulk Ports Corporation.
Some of the land within the APSDA is still privately owned, but the majority is owned by the Coordinator
General, the Minister for Economic Development, through Economic Development Queensland, and the
North Queensland Bulk Ports Corporation.
The Wetlands falls almost entirely within the APSDA and adjoins the Abbot Point international port facility
(refer to Figure 6). Almost all the properties that comprise the Wetlands are owned by the Coordinator
General.
Current land use
On site there is extensive grazing (now excluded from Wetland) and the Abbot Point Coal Loading facility
(an international port). In the surrounding areas there is extensive cattle grazing and a large coal facility
and associated infrastructure located to the north of the site (SEWPAC 2010a).
Several residential dwellings exist within and adjacent to the wetland, most of which are owned by the
local graziers (BMT WBM 2012).
Social and Cultural Values
Traditional Owners
The Wetlands lies within the traditional homelands of the Juru people (NQDT 2011). The Abbot Point EMP
(2010) stated that there are three Aboriginal cultural heritage sites listed for the Abbot Point Area, which
are a fish trap, artefact scatter and a shell midden.
Recreation and Tourism
The lake was formally an important water fowl hunting area for the local community (SEWPAC 2010a).
Access constraints limit recreation and tourism activities associated with the Wetland. It is not promoted
as an area of interest to tourist and not known to represent a key bird watching area or important fishing
area for charter operators (BMT WBM 2012).

Fisheries Resource Values
The Wetlands itself is not known to represent an important fishing area for commercial fishing activities.
However, it potentially provides a large area of breeding and nursery habitat for important commercial
species, one of those being Barramundi (Lates calcarifer) (BMT WBM 2012).
Immediately adjacent to the Wetlands is a range of marine habitats (seagrass, reefs, etc) of potential
fisheries significance. BMT WBM (2012) analysed commercial catch data for the entire Abbot Point area
for period 1998-2003, analysis showed that finfish catches were dominated by mackerel species, which
together represented 49 per cent of the total catch. Of the mackerel catch, 49 per cent were spotted
mackerel, followed by Spanish Mackerel (29 per cent of catch), unspecified (20 per cent of catch) and
Grey Mackerel (6 per cent of catch). The shark fishery represented ~41 per cent of the total finfish catch,
whereas cod (predominantly Coral Trout) represented 3 per cent of the total catch. All other finfish
species represented less than 2 per cent of the total finfish catch. Shellfish catches were more evenly
distributed among species than finfish. In terms of prawns, Tiger Prawns represented the highest
proportion (~41 per cent) of the total shellfish catch, followed by King Prawns (15 per cent), Endeavour
Prawns (4 per cent) and Banana Prawns (3 per cent). Mud Scallops represented 22 per cent of the total
shellfish catch, while bugs (11 per cent) and saucer scallops (3 per cent) represented smaller proportions
of the total catch.
Human Modifications
Development
Port of Abbot Point Coal Terminal
The Port of Abbot Point is located 25 km north of Bowen and is located in the top north east corner of the
Caley Valley Wetlands. It came in to operation in 1984 (NQBP 2012). The Port comprises of rail in-loading
facilities, coal handling and stockpiling areas and a single trestle jetty (T1) and conveyor connecting to two
offshore berths and two ship loaders, all 2.8 km offshore (NQBP 2012). The current export capacity of the
port is 50 Mtpa, however the actual amount of coal exported from Abbot Point Port is significantly less
than this. In 2013/2014 T1 exported 22.89 Mtpa of coal (45 per cent of its capacity).
The scale of proposed port expansions at Abbot Point Coal Terminal is enormous (Figure 7). Two major
terminal expansions have been approved for the area, referred to as Terminal 0 and Terminal 3. A third
terminal (T2) proposed for the area has been withdrawn by BHP. Two additional developments, Abbot
Point Expansion Project (AP-X) and Waratah Coal terminal, have also been proposed for south of the
Caley Valley Wetlands. Combined these port expansion projects will create one of the world’s largest
ports across the Caley Valley Wetlands and on the doorstep of the Great Barrier Reef.
Figure 7. Abbot Point expansion projects - T0-T3 and AP-X (source: Aurecon 2012)
Below is a brief overview of the proposed terminals.
- Terminal 0 (T0)
o Proposed by Indian Adani Group, is adjacent to its existing Terminal 1 at the Port of
Abbot Point. The 70 Mtpa expansion has approval from the Federal and Queensland Government.
- Terminal 2 (T2)
o Proposed by BHP Billiton Metcoal, this 60 Mtpa expansion proposal has been withdrawn
by the proponent.
- Terminal 3 (T3)
o Proposed by GVK Hancock – a joint venture between Indian resources company, GVK and
Gina Reinhart’s Hancock Coal- this 60 Mtpa expansion proposal has approval from the
Federal Minister for Environment and the Coordinator General.
- Abbot Point Expansion Project (AP-X)
o Alternative expansion project to previous proposals which included the Multi-Cargo
Facility (MCF) and the T4-T9 proposal. Preferred proponents are being shortlisted and
concept plan A for the first stage shows the proposed location of terminal to the south of
the Wetlands and a multi user corridor across the Wetlands.
- Waratah Coal
o Waratah Coal Pty Ltd proposes to construct a new coal export facility for the export of up
to 240 million tonnes of coal per year, at the Port of Abbot Point. This proposal was to
occur south of the wetlands, with infrastructure across the wetlands. Recently Waratah
has lodged an application with State Government to be preferred developer of Terminal 2
instead. Neither have approval to date.
The existing port places a number of real and potential risks for the Caley Valley Wetlands and their
wildlife. The enormous expansion proposed for the port would increase these risks. Below is a summary
of key impacts from the existing and proposed port developments.
Water Quality and Dust
Sediment and nutrient increases from changed land use has resulted in lower water quality in creeks and
groundwater. These include direct land use impacts such as the erosion of grazed lands, and indirect
impacts such as the erosion of channel bed and banks have contributed to the decline of creek and
groundwater quality, which has also contributed to elevated pollutant levels (BMT WBM 2012). Dissolved
oxygen, essential for aquatic fauna, is also likely to have declined as increased nutrients from the
catchment are washed into creeks during storm events triggering algal blooms. A dense mat of algal
growth was identified in the BMT WBM (2012) survey, covering the majority of the substrate. Treated
surface water runoff from the Abbot Point Coal Terminal (APCT) located to the north is likely to affect
water quality, and runoff from the elevated dunes and ridges within the APCT which enter the Wetlands
from the east (GHD 2009).
Dust originating from industrial areas may also be a potential source of pollutants. Stormwater (and dust)
from future industrial and infrastructure development within the APSDA post development will be the key
mechanism for transporting diffuse pollutants to the waterways with nutrients, sediments and gross
pollutants being the primary pollutants of concern (BMT WBM 2012). Coal dust and leachate have the
potential to alter water chemistry and in extreme cases poison or smother organisms.

Invasive species
There is the potential for invading exotic species through over 60 bulk carriers per year visiting the area,
discharging approximately 30,000 tonnes of ballast water per carrier per visit (SEWPAC 2010a). Studies
have been undertaken on the ballast water of 23 bulk carriers which were tested and found to have 57
taxa of marine organisms (SEWPAC 2010a). It is estimated that most of the ballast water discharge in
Queensland waters occurs at Hay Point, Abbot Point and Weipa (SEWPAC 2010a).
Light Pollution
Artificial lighting or “ecological light pollution” can have serious impacts on both terrestrial and aquatic
fauna and flora (Deda et al 2007).
Fauna
Light pollution is known to confound animal navigation, change competitive interactions, alter predator-
prey relations, and affect an animal’s physiology (Deda et al 2007).
Marine turtles are dependent on visual brightness cues for orientation and are disrupted by artificial
lighting close to nesting beaches which can have serious impacts on hatchling survival, discouraging adult
females from nesting, and affect female turtles searching for nest locations (Deda et al 2007; Kamrowski
et al 2012). Female nesting turtles avoid illuminated beaches, thereby nesting in less illuminated and
shaded parts, which can affect the number and sex ratio of hatchlings produced (Deda et al 2007).
Artificial light is known to attract migratory and non-migratory birds at night, particularly on foggy or
cloudy nights (Deda et al 2007). Petrels and shearwaters are very sensitive to artificial lights with
fledglings attracted to lights during their first flight to sea, causing some to fall to the ground with fatal
injuries (Le Corre et al 2002). Day active predatory birds and reptiles will forage under artificial lights
(Longcore and Rich 2004) providing a competitive advantage which may have detrimental effects to
existing and new predator-prey interactions (Wildlands CPR 2007).
Near-shore lighting at Abbot Point could cause sea turtle hatchlings to become disoriented when they are
trying to make their way to the ocean, reducing their chances of survival. Credit: Kjersti Joergensen

Flora
Plants use darkness to manage their metabolism, development and life programmes (Deda et al 2007).
Trees need to adjust to seasonal alterations, and artificial light hinders this and can keep various trees
from losing their leaves by light pollution (Deda et al 2007).
Noise
Excessive and loud intermittent noise can cause flight responses in fauna such as shorebirds or avoidance
of areas in the vicinity of its source. The effects of disturbance vary among shorebird species with the
Eastern Curlew being the most readily disturbed (QPWS 2005). Shorebirds use up critical energy when
they take flight due to disturbance which means they might not gain enough condition for migration
and/or breeding (QPWS 2005). Repeated disturbance also exacerbates this problem. For migratory birds
disturbance is most critical during March/April before they migrate, and in September/October when they
return and are recovering from the long flight (QPWS 2005). Resident shorebird species are sensitive to
human disturbance, predation by cats, dogs and feral pigs which may reduce breeding success (QPWS
2005). There is potential for noise associated with the port facility to disrupt wildlife (SEWPAC 2010a).
Traffic
Many wetland fauna species are sensitive to pedestrian and vehicle traffic. Frequent disturbance of
nesting birds may lead to abandonment of the nest and wader birds will lose condition if they are unable
to feed undisturbed. Furthermore, motor vehicles may directly damage eggs and ground dwelling chicks
that are unable to move from their nests. BMT WBM (2012) field surveys identified tyre marks adjacent to
the important Little Tern nesting area at the mouth of Mount Stuart Creek, adjacent to the Wetlands.
Bund walls
There are two major bund walls in the Wetland, causeway (inner) bund and western (outer) bund.
One of the barriers (known as the outer bund) is located across Mount Stuart Creek. The outer bund is
thought to have been constructed to improve habitat values for waterfowl. The outer bund partially
isolates the site from tidal influences, and is likely to impede the movement of aquatic fauna such as fish.
This appears to have resulted in localised mangrove die-back of approximately 46 ha (BMT WBM 2012).
The bund wall was built in the 1950’s by duck shooters wanting to alter the area for hunting. The wall is
less than a metre high and broken in many places, with water flowing over the wall in the wet season.
The inner bund is located east (upstream) of the outer bund, and incorporates a water delivery pipe line
to the Port of Abbot Point and vehicle access (GHD 2009). The effects of the inner bund on wetland
hydrology, water quality and ecology have not been investigated in detail to date (BMT WBM 2012).
The western (outer) and causeway (inner) bunds have modified the ecological character of the Wetlands
through:
Changing tidal hydraulics and associated water quality modifications – including salinity
levels immediately down-slope of the western (outer) bund are greater than seawater;
Changes to vegetation communities - including mangrove dieback immediately west of
the western (outer) bund;
Restricting aquatic fauna movement patterns; and
Barrier for fish movement between sea and Wetlands, and within – limiting habitat values
to species that migrate between freshwater and marine in life-cycle (e.g. barramundi)
(BMT WBM 2012)

The proposed expansion at the Port of Abbot Point will further remove parts of the Wetland habitats, increase noise
and pollution in the area, and threaten the survival of many important species. Credit APAG
Land clearing
Since European settlement, the Wetlands area has been extensively cleared of open forest and
woodlands in favour of grassland for grazing, resulting in the loss of and fragmentation of habitats.
Clearing is likely to have resulted in reductions in the diversity of fauna of the area, particularly those
species which are forest and woodland specialists. It also makes the fauna residing within the remaining
patches of forest and woodland more prone to predation or displacement by more aggressive species.
Grazing
Much of the cleared areas of the Don River catchment have been converted to grazing lands for cattle.
Inappropriate grazing regimes have led to severe impacts on the beach scrub communities at the
southern part of the Wetland. These have also been isolated by an access road and rail link to Abbot Point
coal loading facility (SEWPAC 2010a).
Until recently (2011), cattle were able to access wetland habitats, which is likely to have resulted in a
range of pressures to vegetation communities, such as increased weed infestations, land degradation
through compaction and erosion, and high nutrient loads from cattle waste. Cattle have now been
excluded from lands owned by the Coordinator General, which includes large parts of the Wetlands (BMT
WBM 2012).
Weeds
Weeds displace endemic flora by out-competing them for space, light and nutrients. Numerous non-
endemic plant species (i.e. weeds) have been recorded in the Wetlands. Heavy infestations of introduced
pasture grasses were recorded, including Guinea Grass (Megathyrsus maximus) and Buffel Grass
(Pennisetum ciliare), by BMT WBM (2012) surveys.
Page 39 of 51
Fourteen plant species listed under the Land Protection (Pest and Stock Route Management Act 2002)
and Weeds of National Significance (WONS) have been recorded in the Wetlands (BMT WBM 2012). BMT
WBM (2012) recorded dense infestations of Rubber Vine (Cryptostegia grandiflora) and Prickly Acacia
(Acacia nilotica) (both WONS) around the margins of the Wetlands and along the banks of Saltwater
Creek. Lesser infestations of Parkinsonia (Parkinsonia aculeata), Mimosa Bush (Acacia farnesiana),
Lantana (Lantana camara), Brazilian Nightshade (Solanum seaforthianum), Noogoora Burr (Xanthium
pungens) and Buffel Grass (Pennisetum ciliare) all of which are serious environmental weeds (SEWPAC
2010a and BMT WBM 2012).
Feral Animals
Feral pigs are the most abundant and destructive feral animal in the Wetlands. They destroy vegetation,
modify land through trampling, and are potential predators to ground nesting birds. BMT WBM (2012)
surveys located footprints in a number of locations along Saltwater Creek and on mudflats of Branch
Creek. Rabbits, Red Fox, Black Rat, House Mouse, Common Starling and Cane Toads have also been
recorded in the Wetlands. Feral cats, Common Myna and Asian House Geckoes are also likely to inhabit
the Wetland. Common Myna and Common Starlings are aggressive birds which compete with native
species for nest hollows and food (BMT WBM 2012).
Recommended next steps
Further research
This report is only a preliminary study into the international significance of the Caley Valley Wetlands
based on the small pool of existing research. The majority of the surveys undertaken on the Wetlands
were inadequate in reporting on seasonal variations, vegetation community structure, fauna distribution
and habitat usage, and water quality of the Wetlands. Few broad scale surveys have been undertaken
across the entire study area, providing inadequate data to determine quantitative patterns in natural
variability and species abundance.
Further research needs to be undertaken to collate past and present surveys of the Wetlands including
assessments completed for development impact studies and those undertaken by conservation and
interests groups in the area. The general consensus from previous studies of the Wetlands is the need for
a detailed broad scale survey across the entire site conducted throughout several times of the year to
encompass seasonal and natural variability. This research is greatly needed before the real and potential
impacts of any port expansion projects can be assessed for approval.
Conclusion The Caley Valley Wetlands represents one of the few remaining intact wetland systems between
Townsville and Bowen, supporting a valuable habitat and wildlife corridor for a range of threatened flora
and fauna species. The Wetlands are both nationally and internationally important as they provide
breeding and feeding habitats for a significant number of waterbirds including at least ten that are
threatened.
One of the major concerns for the Wetlands is the proposed expansion of the Port of Abbot Point.
Proposed port developments are likely to further remove parts of the Wetland habitats, increase noise
and pollution in the area, and threaten the survival of many important species.
Page 40 of 51
Through the assessment of previous surveys on the Caley Valley Wetlands and the Abbot Point area, the
Wetlands is likely to meet at least seven out of the nine Ramsar criteria, easily satisfying its potential for
nomination. The Caley Valley Wetlands is internationally significant and its qualification for Ramsar listing
makes it an inappropriate location for the proposed port expansions.

APPENDIX A – DIWA Criteria
DIWA Criteria for determining nationally important wetlands The Directory not only identifies nationally important wetlands, it provides a substantial knowledge base
of what defines wetlands, their variety, and the many Flora and Fauna species that depend on them. In
addition, it contains information about their social and cultural values and some of the ecosystem services
and benefits they provide. It is a valuable tool for managers and others interested in Australia's important
wetlands.
Criteria for determining nationally important wetlands The criteria for determining nationally important wetlands in Australia, and hence their eligibility for
inclusion in the Directory, are those agreed to by the ANZECC Wetlands Network in 1994.
A wetland may be considered nationally important if it meets at least one of the following criteria:
1. It is a good example of a wetland type occurring within a biogeographic region in Australia.
2. It is a wetland which plays an important ecological or hydrological role in the natural functioning
of a major wetland system/complex.
3. It is a wetland which is important as the habitat for animal taxa at a vulnerable stage in their life
cycles, or provides a refuge when adverse conditions such as drought prevail.
4. The wetland supports 1% or more of the national populations of any native plant or animal taxa.
5. The wetland supports native plant or animal taxa or communities which are considered
endangered or vulnerable at the national level.
6. The wetland is of outstanding historical or cultural significance.
Application of the criteria to individual wetland sites involves a degree of subjectivity. Not only may
certain aspects of a site's significance be interpreted differently by different investigators, but information
gaps often exist which make it difficult to judge whether or not a site meets a particular criterion.
Adoption of a bioregional approach to listing sites in the Directory is seen as one way of reducing the
difficulty in applying the criterion relating to a system's uniqueness or representativeness. The Natural
Resource Policies and Programs Committee in 2008 agreed to adopt the Australian Drainage Divisions
system, along with IMCRA for marine ecosystems, as the best fit national regionalization approach for
aquatic ecosystems.
Directory Wetland classification system
The wetland classification system used in the Directory identifies 40 different wetland types in three
categories:
A. Marine and Coastal Zone wetlands
B. Inland wetlands, and
C. Human-made wetlands.
This system was agreed to by the then ANZECC Wetlands Network in 1994. It is based on that used by the
Ramsar Convention in describing Wetlands of International Importance, but was modified slightly to suit
the Australian situation in describing wetlands of national importance.
A. Marine and coastal zone wetlands
1. Marine waters - permanent shallow waters less than six metres deep at low tide; includes sea
bays, straits.
2. Subtidal aquatic beds; includes kelp beds, seagrasses, tropical marine meadows.
3. Coral reefs.

APPENDIX B – Ramsar Criteria
Ramsar Criteria for identifying Wetlands of International Importance Under the Ramsar Criteria, wetlands should be selected for the Ramsar List on account of their
international significance in terms of the biodiversity and uniqueness of their ecology, botany, zoology,
limnology or hydrology. In addition, the Criteria indicates that in the first instance, wetlands of
international importance to waterbirds at any season should be included on the Ramsar List.
Guidance on the application of the Criteria for identifying Wetlands of International Importance is provide
under the Ramsar Convention's Strategic Framework for the List of Wetlands of International Importance,
edition 2009 .
Group A of the Criteria. Sites containing representative, rare or unique wetland types
Criterion 1: A wetland should be considered internationally important if it contains a representative, rare,
or unique example of a natural or near-natural wetland type found within the appropriate biogeographic
region.
Group B of the Criteria. Sites of international importance for conserving biological diversity
Criteria based on species and ecological communities
Criterion 2: A wetland should be considered internationally important if it supports vulnerable,
endangered, or critically endangered species or threatened ecological communities.
Criterion 3: A wetland should be considered internationally important if it supports populations of plant
and/or animal species important for maintaining the biological diversity of a particular biogeographic
region.
Criterion 4: A wetland should be considered internationally important if it supports plant and/or animal
species at a critical stage in their life cycles, or provides refuge during adverse conditions.
Specific criteria based on waterbirds
Criterion 5: A wetland should be considered internationally important if it regularly supports 20,000 or
more waterbirds.
Criterion 6: A wetland should be considered internationally important if it regularly supports 1% of the
individuals in a population of one species or subspecies of waterbird.
Specific criteria based on fish
Criterion 7: A wetland should be considered internationally important if it supports a significant
proportion of indigenous fish subspecies, species or families, life-history stages, species interactions
and/or populations that are representative of wetland benefits and/or values and thereby contributes to
global biological diversity.
Criterion 8: A wetland should be considered internationally important if it is an important source of food
for fishes, spawning ground, nursery and/or migration path on which fish stocks, either within the
wetland or elsewhere, depend.
Specific criteria based on other taxa
Criterion 9: A wetland should be considered internationally important if it regularly supports 1% of the
individuals in a population of one species or subspecies of wetland-dependent non-avian animal species.

Criteria for inclusion in DIWA: 1: It is a good example of a wetland type occurring within a
biogeographic region in Australia.
2: It is a wetland which plays an important ecological or hydrological
role in the natural functioning of a major wetland system/complex.
3: It is a wetland which is important as the habitat for animal taxa at a
vulnerable stage in their life cycles, or provides a refuge when adverse
conditions such as drought prevail.
5: The wetland supports native plant or animal taxa or communities
which are considered endangered or vulnerable at the national level. 2
